    abstract = "The separation of Cr(III) from collagen in chromium-tanned leather (wet-blue) is achieved by a combination of the protein (collagen) stabilization (protective cross-linking) and a subsequent labilization of the Cr(III) species bound to the protein. During the separation collagen retains the tertiary triple helical and higher (fibril) structures. The model proposed for the protective cross-linking involves inter- rather than intramolecular bridging, that is, a supramolecular bridging. The process of chromium removal takes place in a restricted aqueous environment, and it can be characterized as semihomogeneous or semiheterogeneous. © 1998 Air and Waste Management Association."
